This study analyzes the defects associated with nonconformities in the manufacturing process of automotive trunk floors. The work begins with the collection and analysis of data from the final inspection stage, which enabled the identification of the most recurrent defect in the finished product. Based on this finding, the study focused on the production stage most strongly related to the occurrence of the defect. A targeted sampling and a process capability analysis were conducted to evaluate whether the process meets the established specification limits. The capability analysis demonstrated that the process lacks sufficient capability to comply with the required specifications, prompting the implementation of improvement tools such as the Ishikawa diagram, the 5 Whys method, and the Failure Mode and Effects Analysis (FMEA). These tools made it possible to identify the critical conditions contributing to the defect and to develop improvement actions aimed at increasing process stability and overall performance.
